Description

Technical Field

[0001] This utility model belongs to the field of construction site guardrail technology, and in particular relates to a guardrail with an adjustable tilt angle. Background Technology

[0002] Construction site guardrails are an important part of construction site safety management, used to protect the safety of workers and the public and prevent accidents.

[0003] Currently used guardrails are generally horizontally arranged. However, construction sites are subject to varying terrain conditions. Some construction sites require guardrails on sloping ground to protect objects or buildings. When the current guardrails are placed on sloping ground, a large gap is formed between the bottom of the guardrail and the lower part of the ground. Small animals can easily pass through this gap and enter the construction site, causing unnecessary trouble. In addition, some construction sites use multiple detachable guardrails on sloping ground, connecting adjacent guardrails with wire or other structures. However, this connection method makes it difficult to guarantee the installation strength of the guardrails, which can easily lead to guardrail failure. Therefore, existing construction site guardrails need to be improved. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a guardrail with an adjustable tilt angle. This guardrail can adjust its overall tilt angle according to the slope of the ground, allowing it to adapt to the ground and ensuring the installation strength of the guardrail.

[0005] In view of this, the present invention provides a guardrail with an adjustable tilt angle, comprising:

[0006] Support columns, which can be fixedly installed on the ground;

[0007] Mounting base, the mounting base is set on the support column;

[0008] The adjusting frame is rotatably connected to the mounting base in the middle, and both ends of the adjusting frame are provided with connecting parts;

[0009] The locking element is mounted on the mounting base. The locking element can lock or release the adjusting bracket. When the adjusting bracket is locked, the adjusting bracket cannot rotate relative to the mounting base. When the adjusting bracket is released, the adjusting bracket can rotate relative to the mounting base.

[0010] The baffle has a bottom contour that fits the ground, and both ends of the baffle can be connected to the connecting part.

[0011] In this technical solution, the support column is fixed to the ground, and then the locking device is released from the adjusting frame. At this time, the adjusting frame is rotated at a certain angle relative to the mounting base so that the angle of the adjusting frame matches the slope of the ground. Then, the locking device is locked to the adjusting frame. Then, one end of the baffle is connected to the connecting part of one end of the adjusting frame so that the baffle is fixed to the end of the adjusting frame. Baffles are installed at both ends of the adjusting frame, thus forming a simple guardrail. The end of the baffle away from the adjusting frame can be connected to the adjusting frame on another support column. According to this connection method, guardrails of different lengths can be assembled as needed.

[0012] In the above technical solution, furthermore, multiple mounting seats are provided on the support column at intervals along the axial direction.

[0013] In the above technical solution, furthermore, both the mounting base and the adjusting bracket are provided with mounting through holes in the middle, and the locking component includes a locking screw and a locking nut. The threaded end of the locking screw passes through the two mounting through holes in sequence and is threadedly connected to the locking nut.

[0014] In the above technical solution, the connecting part further includes two connecting through holes penetrating the two opposite side walls of the adjusting frame and threaded fasteners. The baffle is provided with two mating through holes that cooperate with the connecting through holes. The mating through holes penetrate the two opposite side walls of the baffle. The threaded fasteners, connecting through holes and mating through holes cooperate with each other to fix the baffle at the end of the adjusting frame.

[0015] In the above technical solution, further, the end of the adjustment frame is provided with an installation groove, the installation groove penetrates the end side wall of the adjustment frame, the connecting through hole connects to the installation groove, and the end of the baffle can enter the installation groove.

[0016] In the above technical solution, a fixing sleeve is further provided on the mounting base. The fixing sleeve can be fitted onto the outer wall of the support column. Fixing through holes are provided on both the side wall of the fixing sleeve and the side wall of the support column. Threaded fasteners are provided between the fixing sleeve and the support column. The threaded fasteners can cooperate with the two fixing through holes to fix the fixing sleeve onto the support column.

[0017] Furthermore, in the above technical solution, the bottom of the support column is provided with a detachable mounting end, which is fixedly connected to the ground.

[0018] In the above technical solution, the bottom of the mounting end is further conical.

[0019] Furthermore, in the above technical solution, the bottom surface of the installation end is adapted to the ground.

[0020] The beneficial effects of this utility model are:

[0021] 1. By cooperating with the adjusting frame and the mounting base, the adjusting frame can adjust the angle relative to the mounting base. The baffle is installed at the end of the adjusting frame, and the bottom of the baffle is adapted to the ground. In this way, when the guardrail is installed in a location with a certain slope on the construction site, the baffle can isolate the environment on both sides, and there will only be a small gap between the baffle and the ground, which can block small animals. In addition, the entire guardrail is fixed to the ground by the support columns, which can ensure the overall installation strength of the guardrail.

[0022] 2. By setting multiple mounting seats at axial intervals on the support column, the adjustment brackets on the multiple mounting seats can be connected and fixed at multiple points on the baffle, which further improves the structural strength of the guardrail.

[0023] 3. By designing the locking mechanism as a combination of a locking screw and a locking nut, when the angle of the adjusting bracket needs to be adjusted, simply loosen the locking nut; when the adjusting bracket needs to be locked to the mounting base, simply tighten the locking nut. The operation is simple and the adjustment is convenient. Attached Figure Description

It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0035] Example 1

[0036] This embodiment provides a guardrail with an adjustable tilt angle, including: a support post 1, a mounting base 2, an adjusting frame 3, a locking component 5, and a baffle 6;

[0037] In this embodiment, the support column 1 can be a solid column or a hollow tube. The bottom of the support column 1 is provided with a detachable mounting end 101. Any method that can achieve a detachable connection between two objects in the prior art can be used as the connection method between the support column 1 and the mounting end 101 in this embodiment, such as a threaded connection.

[0038] The mounting end 101 can be fixedly connected to the ground. Specifically, when the ground where the guardrail is installed is a relatively soft surface such as soil, the bottom of the mounting end 101 can be conical. In this case, inserting the bottom of the mounting end 101 into the ground will fix the support column 1 to the ground. When the ground where the guardrail is installed is a relatively hard surface, the bottom surface of the mounting end 101 can be designed to match the slope of the ground. In this case, the mounting end 101 can have a large weight. For example, some stones can be fixed on the mounting end 101 so that the support column 1 can be placed stably on the ground.

[0039] Please see Figure 1 or Figure 2 The mounting base 2 is L-shaped in general, with a horizontal section and a vertical section. The horizontal section of the mounting base 2 is connected to the support column 1. The mounting base 2 can be fixed on the support column 1 or detachably connected to the support column 1.

[0040] Please see Figure 4 and Figure 5 The adjustment frame 3 is T-shaped as a whole. The middle part of the adjustment frame 3 is rotatably connected to the vertical section of the mounting base 2. Both ends of the adjustment frame 3 are provided with connecting parts 4.

[0041] The locking element 5 is provided on the mounting base 2. The locking element 5 can lock or release the adjusting frame 3. When the adjusting frame 3 is locked, the adjusting frame 3 cannot rotate relative to the mounting base 2. When the adjusting frame 3 is released, the adjusting frame 3 can rotate relative to the mounting base 2.

[0042] Please see Figure 2 The bottom contour of the baffle 6 is adapted to the slope of the ground. The material of the baffle 6 can be plastic, wood or steel. The bottom contour of the baffle 6 can be cut on the construction site according to the slope of the ground. Both ends of the baffle 6 can be connected to the connecting part 4. After the end of the baffle 6 is connected to the connecting part 4, the baffle 6 is fixed on the adjusting frame 3. Any method that can realize the detachable connection between two objects in the prior art can be used as the connecting part 4 in this embodiment.

[0043] The baffle 6 shown in the attached figure is an overall closed structure. In addition, the baffle 6 can also be designed as a mesh or other practical structure.

[0044] For the first assembly method of the guardrail in this embodiment, please refer to Figure 1A mounting base 2 is fixed on a support column 1. After adjusting the angle of the adjustment frame 3 according to the slope of the ground and locking it with the locking piece 5, a baffle 6 is installed at both ends of the adjustment frame 3. The end of the baffle 6 away from the adjustment frame 3 can be connected to the mounting base 2 on another support column 1. According to this connection method, multiple support columns 1, mounting bases 2, adjustment frames 3, locking pieces 5 and baffles 6 can be used as needed to assemble guardrails of different lengths. After assembling the guardrail of the required length, all the support columns 1 can be fixed together on the ground.

[0045] Figure 1 The mounting base 2 shown is installed on the top of the support column 1. Of course, the mounting base 2 can also be installed in the middle or bottom of the support column 1.

[0046] As a second assembly method for the guardrail in this embodiment, please refer to Figure 2 The difference between the second assembly method and the first assembly method is that in the second assembly method, multiple mounting seats 2 are set in the axial direction of the support column 1. Each mounting seat 2 is equipped with an adjustment frame 3 and a locking part 5. In this way, when the baffle 6 is installed to the end of the adjustment frame 3, the adjustment frames 3 on the multiple mounting seats 2 can be connected and fixed at multiple points on the baffle 6, which improves the structural strength of the guardrail.

[0047] Figure 2 The support column 1 shown in the image has two mounting seats 2, which are symmetrically distributed. Of course, more mounting seats 2 can be installed on the support column 1, and the two adjacent mounting seats 2 do not have to be symmetrically distributed.
